In any case I just realised I have little to no knowledge of Diamond Firetail genetics, and a search of the Internet has turned up very little concrete information. What I am searching for is a list of mutations and their type (sex-linked, autosomal recessive, etc.). I would also like to know how the different mutations interact, i.e., do they affect the same gene allele (like a Gouldian's chest colour gene pair expressing a paired combination among purple, lilac, and white), do they affect different alleles independently (i.e. for the Star Finch, the Fawn and Cinnamon genes are separate and operate independently, and thus a Star Finch can be both phenotypically fawn and cinnamon), or do they affect different alleles but dependently (like the Gouldian's Yellow head gene being controlled by the separate Red-Black head gene).
So far the list of Diamond Firetail mutations I've gathered is:
Yellow Tail: autosomal recessive.
Fawn: one site says sex-linked recessive, while another states autosomal recessive.
Cinnamon: sex-linked recessive.
Isabel: sex-linked
Pastel: autosomal recessive
Pied: ??
Silver: ??
White: ??
What I would like to ask the forum is:
(1) Are the above classifications (sex-linked or autosomal) correct?
(2) Are pied, silver, and white, sex-linked or autosomal?
(3) How do fawn, cinnamon, isabel, pastel, silver, and white interact? How many alleles are affected here? For several mutations affecting the same allele, which is dominant? I.e., is it possible to have a fawn and cinnamon Diamond (like a Star finch)? Or both fawn and silver?
Also, while I have your attention, what is this mutation:
According to my notes this guy does not fit any of the mutations fawn, cinnamon, isabel, or pastel.
As always, thanks in advance for your comments.
